David Cameron is believed to be preparing more measures to reduce the penetration of internet porn into our brains, with the PM said to be favouring a plan that would see internet users asked if they had kids when switching ISP.

Answer that question with a "yes" and you'll automatically be taken through the filtering and blocking set-up process, with updated anti-porn systems letting parents impose time-of-day limits on accessing material as well as some more sweeping porn-blocking features. Even the option to limit access to social networking sites will be included in the sweeping new blocking rules.

According to the Daily Mail, ministers will ask ISPs to somehow manage the admin process as well, requiring providers to ensure those setting up the filtering tools are over 18. [Telegraph]
